H.323 Trunk-to-Trunk routing with CUCM 9-10 - Best way to program?
Looking for some expert guidance on the best way to implement trunk-to-trunk call routing in CUCM. By "best" I mean user friendly/manageable/efficient etc...
Here's the application: Inbound TDM calls will be hitting a large, H.323 gateway with 10-digit DNIS. I need CUCM to recognize the dialed number, then immediately route the call back out one of several smaller, H.323 gateways (depending on the dialed number) while passing the original dialed number to the system at the receiving end of the call.
The inventory of dialed numbers is large, and routing changes to individual numbers will be made by non-technical staff; so I would prefer to maintain the routing rules in CUCM rather than in the gateways.
One other layer of complexity: I need the ability to route the calls to destinations that may include only a single gateway, or span multiple gateways.
Any suggestions for a best way to implement this in CUCM would be greatly appreciated.
